Which SBM for the Mopar vehicle

Now needed engine size for a given hp/tq. For a normal driving street only focus car, I'd say rpm (powerband) is gonna be the biggest factor, so whatever cid that can make the needed peak hp around 4500-5000 rpms for a 14-15 second car. Probably whatever the driving weight of the car is knock an zero off and your in the ballpark eg.. 3600 lbs = 360 cid.
